GRIP.

SPECIFICATION forming part of Letters Patent No. 407,441, dated July 23,1889. I

Application filed May 25, 1889. Serial No. 312,087. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM JOHNSON, a citizen of the United States,residing at Penn Yan, in the county of Yates and State of New York, haveinvented certain new and useful Improvements in Grip Dies or Shoes forCable-Railway Cars, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to grips for cable railways.

The object of the invention is to produce a die or shoe in which thewearing-piece or faceplate may be quickly removed and replaced, and thecable shall not abrade or wear the holding devices of this plate.

Figure 1 is an end view of so much of the grip as is necessary toillustrate my invention. Fig. 2 is a side view, partly in section, ofone of the dies or shoes with wear-plate in position. Fig. 3 is a faceview of the die or shoe and wear-plate, and Fig. 4 a side view of thewear-plate partly broken away. Fig. 5 is a section on line 5c of Fig. 2;and Fig. 6, a section on line y y, Fig. 2.

A indicates the bar of a well-known form of grip, which extends upthrough the slot of the conduit; and B, the swinging jaw.

C denotes the cable.

The jaw B has a trough-like recess D, which receives a die or shoe E.The back of shoe E has bosses F, which extend into depressions in thejaw B. (See dotted lines, Fig. 1.) The other shoe E is similar to theshoe E, save that it has an inclined piece E which serves to guide thecable into the grip. The shoe E is carried by the jaw opposite the jawB. There is nothing new in the construction of these parts, save as willbe now described.

Instead of making the shoes E E solid, as

has been generally .done, I make a-removable face-piece or wear platefor each one. The shoes E E are of forged or cast metal of considerablestrength. Pockets H H, preferably rectangular, are made in the metalopposite the bosses F, and the face of the shoes or dies E E are groovedfrom end to end, preferably in the form shown in Fig. 5, the pock etsbeing below the level of the groove. fear-plates I I are made withprojections K K on their rear surfaces to fit pockets H II. The faces ofthese wear-plates are grooved to embrace the cable. The face of thewearplate has sunken pockets L L, corresponding with the projections KK. These pockets are preferably rectangular to receive the T heads ofbolts 0, said bolts passing through the plates, dies, or shoes, andgrip-jaws, and being held by nuts P. The sunken pockets L permit thebolt-heads to fall below the wearing-face of plates I, and should bedeep enough to carry the bolt-heads below that part of the wear-platewhich will be worn away by the cable, although a slight wear will do noharm.

The wear of grip-shoes is very rapid. Usually grip-shoes have to bereplaced two or three times a day, and no matter how heavy thewearing-plate may be it must be thrown away after the cable has worninto its face a certain distance. It has been customary in this form ofgrip to make the pieces E and I integral and throw away the entire shoewhen a little worn. By my improvement only the wear-piece I need bethrown away, as the shoe E will last indefinitely, and with myconstruction the fastenings are also protected.

The incline E is allowed to overhang the wear-plate I, so as toprovidean easy guiding-surface for the cable into its seat in the grip,otherwise the upper part of one of the wear-plates would need to beinclined or carry a part of incline E and it is preferable to have thewear-plates alike.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a cable-grip, of a grip-shoe and a removablewear-plate, said shoe and removable wear-plate being held together andattached to the grip by the same means, substantially as described.

2. The combination of the grip-shoe having recesses therein, awear-plate having projections which enter said recesses, and a pocket inits wearing-face and securing-bolts passing through the plate and shoe,and having their heads sunk in said pockets praeti- In testimony whereofI have affixed mysigcally below the depth of wear, substantially naturein presence of two witnesses. as described.
